East Central Iowa | "If you mate a Heterozygous Black 'Bb' bull to a Heterozygous Black 'Bb' cow 4 different times you will get 3 Black calves and 1 Red calf.
1 of the Black calves will be Homozygous Black 'BB' because the calf got a big 'B' from the bull and a big 'B' from the cow.
1 of the Black calves will be Heterozygous Black 'Bb' because it got a big 'B' from the bull and a little 'b' from the cow.
1 of the Black calves will be Heterozygous Black 'Bb' because it got a little 'b' from the bull and a big 'B' form the cow.
The 1 red calf 'bb' got a little 'b' from the bull and a little 'b' from the cow. "
Just to make that clear, these are the odds for each individual calf. Each calf has a 75% chance to be black, and 25% chance of being red. No guarantee that 25% of your calves will be red.
